RE: Goldberg Eagle 2 ARF trainer?????
Yes, it's excellent.
I've been buddy-boxing a guy who has one. He put an OS46AX in it. His Eagle2 is about the best flying trainer of all that I'm flying with students right now. And he's doing very, very good with it.
The only trainer type ARF that I've seen recently that matches up to it, is the KYOSHO Calmato high wing. Truth is, there doesn't seem to be anything magic about either plane's design. They both just happen to have the lightest wing loading and both have 46AXs on them. The Calmato was $105 at the LHS.
About the only thing different between the two is the landing gear. The Eagle had wire and it was constantly bending. I replaced the main with an aluminum replacement one. Think it was a H9 for $10. The Calmato came with a decently strong aluminum main.
